IAT Sensor Resistance
On all models, IAT sensor is part of Mass Airflow (MAF) sensor. Turn ignition off. Disconnect MAF sensor connector. Measure resistance between MAF sensor terminals THA and E2. (Scheme 72) Replace MAF sensor if resistance is not as specified. See INTAKE AIR TEMPERATURE (IAT) SENSOR RESISTANCE table.
| Ambient Temperature °F (°C) | Ohms |
|---|---|
| 4 (-20) | 13,600-18,400 |
| 68 (20) | 2210-2690 |
| 140 (60) | 493-667 |
